Makefile:632: recipe for target 'golangci' failed
make: *** [golangci] Error 2

[nmittler]

I'm seeing this as well. It happens with both 1.15.0 and 1.16.0.

[jeremyje]

I tried older versions seems that 1.12.2 fails more gracefully but 1.13+ does not.
Here's what I get in 1.12

INFO [loader] Go packages loading at mode load deps types and syntax took 1.172983354s 
ERRO Running error: context loading failed: failed to load program with go/packages: /usr/bin/gopackagesdriver: exit status 1: gopkgsdriver: EOF

[listx]

For me if I use 1.10.2 it avoids the panic:

GO111MODULE=on go get github.com/golangci/golangci-lint/cmd/golangci-lint@v1.10.2

I got the idea to use 1.10.2 because it's the newest release before 0421bac which is the last commit to touch vendor/golang.org/x/tools/go/packages/packages.go, which is where the trace starts (I had the same trace).

Googling the keyword loadRecursive turned up this issue: golang/go#31163 which seems to be the same thing.
